Note: Asymmetrical loop CME seen to the W in SOHO LASCO C2/C3. This CME is partially obstructed by a data gap in STEREO A COR2 which lasted from 2025-01-07T17:53Z to 2025-01-08T01:38Z. Source is a large eruption and brightening associated with the long-duration M1.1 flare located just beyond SW limb, likely from AR 3939 (S17W99), as seen in GOES SUVI. Widely opening field lines, brightening, and ejection of material can be seen in GOES SUVI 131/171/195/211/304 starting at about 2025-01-07T22:10Z. The tops of post-eruptive arcades can be seen emerging from beyond the SW limb in GOES SUVI 171 starting at about 2025-01-07T23:48Z. There is some uncertainty in the exact location of this eruption since this is not directly on the disk, but it is very likely associated with Active Region 13939 which is estimated to have been located at roughly S17W99 at the peak time of the flare [2025-01-07T23:05Z].
